Abstract

A method capable of improving the endurance of memory includes: detecting whether a record cell is the last record cell of a set of record cells it belongs to or not; and erasing the data of a corresponding set of multiple-time programmable memory blocks and erasing the set of record cells if the record cell is the last record cell of the set of record cells it belongs to. The method further includes programming a record cell corresponding to the first non-programming one in the set of record cells if the record cell is not the last record cell of the set of record cells it belongs to.
